Abstract
A phosphor blend for a compact fluorescent lamp is described wherein the phosphor blend comprises a green-emitting Tbphosphor, a YO:Euphosphor, a SrBPO:Euphosphor, a MgGeOF:Mnphosphor, and optionally a BaMgAlO:Euphosphor, wherein the blend contains from 1% to 20% by weight of the SrBPO:Euphosphor and from 5% to 30% by weight of the MgGeOF:Mnphosphor. A compact fluorescent lamp having a phosphor coating containing the phosphor blend produces a light that is perceived as more pleasing than the light produced by standard compact fluorescent lamps.
